As far as I can tell, your argument assumes that each individual will find the greatest satisfaction in promoting their own individual survival and wellbeing. Evolutionary theory suggests that this is not necessarily the case, since natural selection acts to create adaptations which promote the survival, not primarily of the individual, but of the individual’s genes, whether in their own offspring or the offspring of others, usually relatives. Evolution often programmes individuals to find satisfaction in looking after other individuals as well as themselves, not necessarily their own offspring. This is crucial in the evolution of cooperation, and humans have clearly evolved as a highly cooperative species.

Of course, claiming that some behaviour or feeling is an evolved predisposition is not to claim that it’s rational. Are you saying that if a person has an evolved predisposition to find satisfaction in looking after some other people’s wellbeing, as well as (or, occasionally, instead of) their own, then this satisfaction is irrational?

(I’m talking about inclusive fitness theory as described by Wikipedia here; there is a consensus among evolutionary biologists that inclusive fitness theory is correct)
